Stand for baby seat

ABSTRACT

A stand for baby seat particularly useful on the back of a lawn mower tractor. The stand comprises a sliding plate at its lower end and a square tube on its upper end. The sliding plate slips into a sleeve fixed on the rear end of the tractor, for that purpose. The square tube receives one end of a positioning tube, adjustable in the square tube. The other end of the positioning tube supports a horizontal plate on which is fixed the baby seat. The baby is then in a position near an adult driver, immediately to the right, to the left or to the back of the driver.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] In the description which follows and the drawings which accompanyit similar numbers refer to identical parts in the various figures.

[0017]FIG. 1 shows a stand 20 ready to use, with a back seat 22, shownin dotted line. Seen from the back, the stand 20 has a T-shape. At itsbottom is a plate 24 sliding into a sleeve 26 fixed by fixation screws40, on a lower portion, at the back of a tractor 28—the rear part of itshown in dotted line—. The sleeve 26 has rectangular edges 76, forparallel entry, or at least forming an acute direction; a blocking screw78 maintains the plate 24 in the sleeve 26. At the upper part of thestand 20 is a square tube 30 equipped with locking pins 32. Apositioning tube 34 slips in the square tube 30 and is locked in placeby the locking pins 32. A plate 36 is fixed at one end of thepositioning tube 34 by positioning screws 38. The plate 36 receives theseat 22 and fixes it firmly and securely. The plate 24 must haveparallel sides and preferably must be a rectangular plate 76.

[0018]FIG. 2 shows the stand 20 installed on a side wall 28′ of thetractor 28. The stand 20 has an L-shaped arm to keep the seat 22 awayfrom the tractor 28 and at a certain height within grasp by the driverparent. The sleeve 26 is fixed by fixation screws 40 onto the rear endof the tractor 28′. The sliding plate 24 is slipped into the sleeve 26.The sliding plate 24 is tilted according to an angle μ 70 with respectto the stand 20 so that the stand 20 and thus the seat be maintainedstraight up despite the slant of the tractor side. The locking pins 32fix the positioning tube 34 in place in the square tube 30. The lockingpin 32 has a head 44. A fastener 42 passes through the head 44 of thepin 32 then through the positioning tube 34 and ties itself at the otherend of the pin 32 to prevent the pin 32 from being shaken off.

[0019]FIG. 3 is a top view of the stand 20. The plate 36, rectangular,is fixed on one of the long sides of the positioning tube 34. The plate36 has small screw holes 72. There are four positioning screws 38, oneat each corner of plate 36 to fix the seat on the apparatus. The sameapplies for the sleeve 26, which has four sleeve holes 46 to receive thefixation screws 40. As for the square tube 30, it has two tubes holes 48to receive the locking pins 32. One also notices the shape of thefastener 42 which has a loop 50 which passes through the head of alocking pin 32.

[0020]FIG. 4 illustrates the way in which the seat 22 is installed onthe plate 36. There are two sizes of positioning screws 38. Two longscrews 52, at the back, pass through the seat 22, the plate 36 and thepositioning tube 34. Two short screws 54, on the front, pass through theseat 22 and the plate 36. The plate 36 shows a collar 56 under the holesthat accommodates a short screw and prevents the play of the shortscrew.

[0021]FIG. 5 shows stand 20 in totality. One notices that the plate 36is fixed on the end of the positioning tube 34 with long screws 52. Onealso sees two short screws 54 in small screw holes 72 and two longscrews 52 in long screw holes 74. One also sees an L-shaped stand with ariser 60 and a horizontal dormant 62 terminated by the sliding plate 24fixed onto the sleeve 26 by means of fixation screws 40. One also seesthe interior 64 of the square tube 30.

OTHER EMBODIMENTS

[0022] The positioning tube is made so that plate 36 can be fixed oneither side of the square tube 30 so that the seat 22 can be installedat the left or the right of the stand 20.

[0023] Another embodiment comprises two plates 36 fixed at the ends on aflat part of the positioning tube 34, which makes it possible to fix twoseats on the support stand. The positioning tube 34 matches in squaretube 30 thanks to a flat part on the top, that which prevents rotationof the plate 36. The tube 30 need not be square in section but must haveat least one flat part and preferably two rectangular flat parts such asan L beam, or three flat parts as for matching a U beam, the positioningtube 34 having corresponding matching sections. It is clearly understoodthat the embodiments of this invention which were described above, inreference to the annexed drawing, were given as an indication and are byno means restrictive. Modifications and adaptations can be made withoutdeviating from the scope of this invention. Other embodiments arepossible and are limited only by the scope of the claims which follow:
